Further to 1: Mounting the tire on the rim
- Remove rubber residues and dried-on tire paste from the rim, especially from the rim bead and the hump.
- Examine rim for damage; remove old balancing weights.
- Use the prescribed tire mounting paste (only TIP TOP Universal, order No. 593 0601, 3.5 kg bucket, or Contifix) so that the tire does not turn on the rim the first time the car is driven, thereby destroying all of the careful work. If the tire turns by as little as 20 mm with respect to the rim, this can worsen an optimum balancing result.
- Mount tire on the rim. When doing so, it is expedient - and necessary in individual cases - to mount the tire in a favorable position with respect to the wheel (matching). Controlled or uncontrolled matching.
- Uncontrolled matching: Turning the tire on the wheel by 90° or 180° if necessary in order to achieve an acceptable value with regard to rolling smoothness (true running, imbalance and distribution of balance weights).
- Controlled matching: With a balancing machine with matching program. In most cases, this produces an even better result with regard to the rolling smoothness (true running, imbalance and distribution of the balance weights) than can be achieved with uncontrolled matching.
- Fill tires to a pressure of approx 4.0 bar. At the latest when the pressure reaches 4.0 bar, the beads must pop up out of the deep bed and over the hump of the wheel shoulder in order to avoid fractures of the bead core. If necessary, interrupt the process and generously coat all necessary surfaces with lubricant (tire mounting paste). Then repeat the process.
- Check the fit of the tire on the rim by means of the bead centering line.
- Set the prescribed tire pressure. See Wheel rims and tires .
